Applejack was content as she worked on the farm bucking apples without a care in the world. As she went about her chores the sounds of flapping wings made her look up. However, due to the afternoon sun, she was only able to see a rough silhouette of the group of pegasi flying over. Judging by the direction she guessed it must have been Fluttershy heading back to her cottage. Focusing back on her work, she failed to see the cloud-like stroller or the diapered Spitfire flying away out of sight.
An hour passed by quickly Applejack having just finished feeding the pigs. Wiping her brow with satisfaction, she made her way back to the farmhouse for a good old glass of apple juice. “Sure could use a drink.” She whistled as she entered the home feeling the cool air of the air conditioner. Letting out a content sigh, she quickly made her way to the bathroom.
Big Mac meanwhile was in the kitchen rubbing his head as he saw a bottle on the table with a note that said, “don’t forget to feed Applejack.”
“Huh? Why would she need a baby bottle and what am I supposed to fill it up with?” He then turned to see a container of formula. Shrugging he filled the bottle with water and the formula before shaking it about before placing it in a pot filled with water to let it warm. “I don’t get why I’m making a bottle for Applejack for?”
Applejack came back from the bathroom sniffing the air. “Oh is that Granny’s special foal formula!” A few sparkles hung over Applejack’s head.
“Oh yeah, it is! It’s almost heated up.” Big Mac explained blushing not knowing why he felt compelled to baby his sister. “Now go on sit down at the table and don’t forget to put on your bib.
“M-my bib?” Applejack rubbed her head before looking at the dinner table. Sitting right where she normally sat was indeed a big pink bib with big white letters that read “sugar cube” she blushed. “Aww, this is what granny calls me all the time.”
Big Mac helped tied it around his sister’s neck and sighed, “Applejack where’s your bonnet? You’re going to get a sunburn if you don’t wear it.”
“I don’t need it,” Applejack whined, not noticing the magic happening around her.
Big Mac was having none of it tying a pink bonnet around his sister’s head. “You stop your fussing young lady.”
She grumbled as he then took out a pair of pull-ups with little apples printed on them. “Now put these on little filly.”
“I’m potty trained! Dun need training pants!” Applejack whined before crossing her hooves.
Big Mac scoffed, “if you don’t wear your pull-ups you're going straight to bed.”
Applejack’s pout grew but Big Mac’s glare made her realize she’d be in big trouble if she didn’t listen. “Fine put them on.”
Mac rolled his eyes as he slipped the pants over his sister’s rump and plopped her on a booster seat that had appeared before placing down a bowl of applesauce and the bottle of formula. “Now eat up!”
Applejack took a spoon and tried to eat the applesauce without making a mess but kept missing her mouth smearing it all over her face and getting some on her bib. The mare whined as she kept trying which just made the mess worse. She let out a whimper feeling small.
Big Mac watched with a smile taking out a little handkerchief and wiping off her face. “Oh, such a messy little filly.”
“Stop! I’m not messy!” Applejack cried out wiggling about. “I’m a big filly.”
Big MAc rolled his eyes. “Well, that bib and your face tell a different story.”
Applejack blushed seeing her bib smeared with applesauce. “Not my fault something is making me messy!”
Big Mac giggled, “oh is it the monster in the closet?”
“Yeah, he’s real and super scary!” The two hardly noticed a pink diaper bag lingering just out of sight in the living room.
“Maybe when your big sister will get home she can help scare away the monster.” Big Mac turned to see Apple Bloom coming back from school. “Oh, Apple Bloom? Can you come over and help do the dishes? I need to clean up Applejack and have her go potty before she takes her nap.”
Apple Bloom was confused scratching her head. “Huh? What's going on!? Applejack why you in training pants, and a bib? And is that a bottle?”
“Because Big Mac made me! I am a big pony I five!” Applejack shouted.
Apple Bloom was about to retort but saw the diaper bag first. She walked over to it puzzled. “Huh? What’s this?” She then spotted a cute pink bow and blushed “oh...well...I was thinking of gettin’ a new bow, need more than red ones.” Taking her old bow off, she began fixing the pink one in her mane. Without realizing it she started to twirl about humming a tune as she cleaned the kitchen.
“Don’t forget your apron Apple Bloom,” Big Mac reminded her, pointing to said apron that lay upon the diaper bag.
“Oh right! Thank you big brother!” she chirped with her voice a lot softer and sounding older. “Huh? Why do I sound so weird?” She took the purple apron off the bag seeing a heart embroidered on the fabric. There was also a green apple in the middle of the heart.
She watched as Big Mac took Applejack by the hoof leading her out of the room to the bathroom. When they returned, he patted Applejack’s head. “Such a big girl going potty on her own.” Big Mac cooed.
“Don’t say that out loud! I don’t need your help going potty!” Applejack whined.
Apple Bloom dawed, “oh she’s so cute trying to act all grown up.”
“But I am a grown-up!” Applejack huffed and started to cry.
Apple Bloom sighed, “oh dear she’s having a tantrum. Maybe we gotta put her down for her nap.”
“No nap! No nap!” Applejack kicked around while laying on her stomach. Big Mac took the bottle of formula from the table and grabbed hold of his sister before plopping it into Applejack’s mouth watched her suckle it down.
“Oh, she just forgot to drink her formula from earlier.” He held her close rubbing Applejack back as she drank which seemed to calm down the big foal. Once he was satisfied she was all calm, he took Applejack upstairs settling her down underneath some blankets in her room. “Now you go on and get some sleep.”
“Ok, thanks, big brother.” Applejack yawned closing her eyes but her mouth kept moving.
Big Mac groaned, “oh I forgot a pacifier?”
He suddenly found a cute one with Applejack’s cutie mark printed on it and placed it in Applejack’s mouth. She sucked it letting it bob up and down.
Big Mac nodded and slowly left the big foal to sleep. The stallion went downstairs and saw it was now spotless with Apple Bloom turning around with a smile. “Oh, Baby Mac where’s your protection?”
“What are you talking about Apple Bloom? I’m not a foal.”
“Aww, trying to be big like your sister how cute.” Apple Bloom came over and took Mac’s hoof. Despite the clear size difference, she was able to tug him over the changing mat that was lying next to the diaper bag. Easily rolling the big lug over onto his back, Apple Bloom began to change him bringing out the large white diaper with green leak guards unfolding the massive garment as it tucked beneath him.
Big Mac whined but could only watch as Apple Bloom powdered his rump and slowly strap him up in the biggest diaper he’d ever seen.
The stallion looked down at the big bulky diaper between his legs and saw the cute little apples printed on the padding he blushed actually liking the look and the feel of his new padding. “Thanks, ma-” His face turned bright pink as Apple Bloom giggled.
“Hehe, you can call me mama if you want to Baby Mac.”
He slowly got up and waddled around shaking his big diaper quite happily.
Apple Bloom gave his padding a few pats and cooed. “Why don’t you go play in the living room I set up a playpen filled with all kinds of toys.”
“Yay Toys!” he squealed and ran off as Apple Bloom followed him.
Granny, who had just woken from her mid-day nap came out from her room and blinked upon seeing Big Mac drooling, bouncing in a diaper (that was stained yellow and a bit saggy) while trying to stack blocks. “What? Am I still dreaming or is Big Mac wearing a diaper.”
“Oh hey Granny, I’m keeping a close eye on the young ones, just like you taught me.” Apple Bloom said with a beaming smile.
“Granny blinked. “What?” she watched Big Mac play. “But ain’t he a bit big for diapers? I potty train you all myself. Not that this site is kind of adorable.”
Apple Bloom giggled “oh that’s silly Granny, I mean look at Baby Mac’s diaper? He obviously needs them.”
Granny squinted seeing that indeed his padding was a bit yellow. “Ah guess you’re right sweet pea. Hehe, pee.” She laughed a bit. “I don’t know what’s going on but it brings back such lovely memories.” She trotted over to Apple Bloom booping her nose. “ I remember when ya were learning to use the potty. Always tryin to flush things down the drain because it was fun. Lost a lot of toothbrushes that year”
Applejack yawned coming down the stairs with her pull-up sagging too. “Big sissy I need a change.”
“Oh Applejack maybe I should've put a diaper on your bed wetter.”
Granny without even batting an eye grabs a spare pair of training pants for the diaper bag and moving over to Applejack ruffling her mane. “Don’t’ you worry sugercube, Granny going to make it all better.”
She hugged her granny and asked, “can we make an apple pie together?”
Big Mac whined, “wanna help too!”
“I don’t know, the kitchen is a might dangerous for a youngin like yall.”
Apple Bloom rolled her eyes. “You just want to eat the batter.”
“Nuh-uh only wanna lick the spoon!”
Granny cooed, “I'll make ya two an apple pie but after your diaper changes now come on.” She took a pink diaper bag and went about cleaning the two up, powdering their rumps, and strapping them in new thick diapers. Applejack whined about being diapered but her granny talked her into it after a while although she still pouted adorably.
Big mac seemed to be regressed more now chewing on his hoof and looking around. Apple Bloom saw what he was doing. “no chewing on your hoof bad Baby Mac.” she plopped a pacifier in his mouth. “These foals just wanna eat everything.”
Applejack took a spare diaper and chewed on it and Granny gasped “no bad baby” she took it and nodded. ”Right gonna have to keep foal locks on the pantry. They at the age of stickin anything in their mouths.” She jingles some keys for the two moving it around as the foals tracked it with amazement.
Apple Bloom pulls out some plastic locks from the diaper bag. “Well, I'll go foal proof things while you keep them busy.” She then skipped off as Granny continued playing with the two foals.
Apple Bloom smiled as she attached foal harnesses to the two big foals cooing. “Since you two have been so well behaved, I think you deserve a treat.” She sang the two foals bouncing with joy. While Bloom was busy with Big Mac, Applejack's eyes were drawn the bag noticing it was glowing a faint orange.
“Ooooh!” Applejack reached out and touched the bag feeling a tingly sensation run down her spine. She laughed gleefully as the colour faded away leaving a light sparkle around it in its place. “Bye-bye orawange.”
Apple Bloom so turned around seeing Applejack poking at the bag. “What was that Applejack? Oh, you probably want your hat.” She carefully removed the pink bonnet from her sister's head before reaching into the bag and pulling out a light pink cowboy hat with white trim. Placing it upon the foal’s head, she pulled the string down and tied it snug around Applejack’s chin. “There, now you'll be nice and safe from the sun.”
Big Mac was being fussy as Granny gave him a quick change. The mare frowned. “Hold still! I can’t change your diaper with you fussing about.”
The stallion kicked and whine acting like a little foal as Applebloom took out a pacifier and plopped it the stallion’s mouth. “Oh, he’s just wants something to suckle.”
“Maybe we should let him take SmartyPants too?” Granny added, “ he sure does love that old thing.”
“Oh good thinking Granny,” Apple Bloom replied, quickly retrieving it from the bag like magic.
While Apple Boom was occupied, Applejack waddled over to the pantry and tried to open it but it wouldn’t budge she plopped on her padded rump and whined, “I hungwy! I want food!”
Granny shook her head. “These foals are eating more than they should they’re going to get fat.”
“At least it is not apple fritters,” Apple Bloom joked, moving to bring Applejack back. “You’ll be getting a snack at the bakery sweetie.”
Applejack looked up and asked, “can I get Apple fritters?”
Granny chuckled, “sure why not?” She tickled Applejack’s tummy. “I’m sure they got just what you want there too.”
Big Mac snuck over to the diaper bag while the others attention was on Applejack and took out a big foal bottle of formula and began to suckle down the creamy milk.
Apple Bloom laughed coming over and helped Big Mac up. “Ok come on, we should get going, you can drink more f your baba later.” She mothered taking hold of the leashes and movin the door.
The trip through town, of course, attracted many eyes to stare and without any convenient candies to use there was nothing to distract them from wondering what was going on.
As soon as they entered the bakery, Pinkie Pie saw the Apple family and squeaked seeing Big Mac and Applejack strapped up in diapers. “Woah!? What's going on here! Oh no is it the bag?!”
“Oh, we just came to get a few snacks for the hungry foals.”
Pinkie gulped seeing the diaper bag and knew that the Apples were under its influence and if she didn’t act fast she would be next for sure. “Oh uh..ok...how about I get you some foal safe cake and bottles of milk?”
“Sounds perfect! We already got milk though.” Apple Bloom chirped, patting the bag gently.
Pinkie threw a hoof. “Oh, foals always need milk, trust me they really need it.” She headed into the kitchen to find the spare bottles they use for the Cakes hoping that was far enough away. “Okay Pinkie think, what do I do?”
Fluttershy came into Sugarcube Corner not much later and gasped upon seeing Applejack and Big Mac in the foalish attire and munching away on small cupcakes getting crumbs and frosting all over the place.
Apple Bloom waved a hoof. “Oh hey Fluttershy! How are things going?” The bag glowed a soft yellow for a few seconds as the pegasus got closer.
Fluttershy gulped with sweat coming down her forehead she needed to not act suspicious and find a way to slip the Apples some coffee. “Oh...um...everything is great...I...I just came to get a cake for my foals.”
“Oh you got foals too, that sounds great! Isn’t Rainbow Dash a ballerina?”
Fluttershy snickered still thinking of how Rainbow is going to wake up in her silly outfit. “Oh yes, she practiced her ballet skills all afternoon and then fell asleep in her cute tutu.”
Applejack’s giggles as she listened. “Ooh, ballerina!” She looked around with joy. “Where ballerina!”
PInkie upon hearing Fluttershy peeked her out of the kitchen. “Oh, Fluttershy you’re here too.”
Fluttershy came over and asked, “Hey pinkie...um...are you feeling ok?”
“Yeah I am but I need to tell you something come over here.” she gestured with her hooves trying to not attract Apple Bloom’s attention.
The pegasus fluttered over to Pinkie and the earth pony explained, “Fluttershy that diaper bag Apple Bloom has is enchanted and is making ponies act weird.”
Fluttershy, however, wasn’t fully paying attention seeing some icing on Pinkie’s face she took a handkerchief from the countertop and wiped the mare’s mouth. “Oh I know, I thought Soarin, Spitfire and Rainbow Dash were my foals for a bit. But I drank some coffee and it snapped me out of it.”
Pinkie blushed a bit at the cleaning finding it felt kind of nice. “Oh that makes sense, the most adult thing is coffee after all.
Fluttershy nodded “right but we have to have them drink it without them noticing or else they might try to leave.” She then eyed Pinkie’s rump. “Um...are you potty trained?”
“Yes I am, I haven’t had an accident all day. Also, I can slip some coffee into the foal’s milk.” Pinkie whispered back and she ran off to fix the foal’s bottles and was also thinking about why Fluttershy would ask her that weird question.
Fluttershy meanwhile, trotted back out to the front of the store watching Applejack and Big Mac playing patty cake while Apple Bloom taught them. The pegasus couldn’t help but wipe the foals' mouths. “You foals are so messy I mean did you eat any of the cake or just mashed it all into mush?”
Apple Bloom sighed, “they’ve been like this since they were born. I don’t think they can feed themselves all that well.”
Fluttershy cooed, “that’s why you have to spoon-feed them silly.” She reached into the diaper bag retrieving a jar of mushy cake.
As Fluttershy kept the apples busy Pinkie was going to pour some coffee into the bottles filled with formula but something was keeping her from putting it in. “Foals shouldn't dr-” she shook her head. “No, that stupid diaper bag is doing this! I have to save Applejack and Big Mac!
She squirmed feeling like she needed to go use the bathroom. “Oh no! I have to go soon!” She did a quick potty dance before zipping off toward the bathroom finding it really hard to hold it leaving the bottle on the counter.
Apple Bloom peeked her head in as soon as Pinkie had left and sees the bottles “Oh there they are” she moved over and snapped the nipples on the bottle before bringing them out leavin h coffee untouched.
As Apple Bloom returned with the bottles, Fluttershy looked over at them and whispered, “I hope Pinkie didn’t put the coffee in there foals shouldn’t have all that caffeine.”
She didn’t notice something yellow energy slowly flowing off her and entering the diaper bag.
As the foals cheered and took their bottles to drink, Pinkie came back with her face a deep red and laned close to Fluttershy whispering. “I...I missed the potty.”
“That's why you should be wearing some protection Pinkie.” Fluttershy shook her head reaching the bag once again and pulling out the light purple training pants with cake patterns on it. She held it open for her friend. “Come on let get these on.”
Pinkie reluctantly let her pull them on and blushed.“Thank you, Fluttershy.”
She ruffled Pinkie’s mane. “It's alright, now go and sit down its lunchtime.” Pinkie Pie plopped down on a chair as Fluttershy continued to feed them the mashed cake. Without realizing it Pinkie saw something pink came from her body and into the diaper bag causing the bag to glow for a moment.
“Oooh, pretty!” Pinkie pointed with glee.
Fluttershy turned to the party pony. “Don’t touch the diaper bag, only big ponies can.”
Apple Bloom scolded her own siblings. “Yeah, that means you two.”
They both nodded and yawned as it seems they were now tired. Apple Bloom turned to Fluttershy and asked, “why don’t we put the foals for a nap?”
“Good idea.” Fluttershy chirped she went about cleaning the foal's mouth one last time and escorted them up the stairs and into Pinkie’s room. The mare tucked them all under the sheets of Pinkie’s bed.
The pegasus nuzzled them and watched the three fell asleep as she rubbed her head. “I swear I feel as if I’m forgetting something?” As she tried to remember, the bag glow changed between orange, yellow, and pink in a slow cycle unseen by the group, something was definitely changing.
